The Lowdown
Alright, Rusty here. Let’s break down what’s ahead for the next couple of weeks.
First up, we’ve got some decent surf rolling in from Tuesday the 21st. The best calls are Tuesday morning and Wednesday morning, with a 5 ft ENE swell and a light offshore breeze – that’s clean, lined up, and fun. The combined wave energy is solid (348 on Tuesday morning, 366 on Wednesday morning), so there’s a bit of grunt to it. The period is short, just under 8 seconds, so it’s a windswell, but with the offshore wind, it’ll still have a bit of shape. Afternoon sessions drop off a little in size, but Wednesday afternoon is still surfable, just a bit ordinary.
Thursday the 23rd is a total dud. Strong WSW wind swings onshore, and the swell drops to 2 ft in the morning, with energy that’s weak (86). Thursday afternoon is even worse, with 25 km/h onshore wind and a tiny 2 ft swell. Friday the 24th is a write-off – a tiny 1 ft SSW swell with glassy conditions in the morning, but it’s just too small. The afternoon goes cross-onshore and messy.
Saturday the 25th is a mixed bag. The morning is a bit of a gamble with light rain and a cross-onshore breeze, but the swell is rebuilding to 4 ft from the south. The afternoon is the better call – the wind swings cross-offshore, the waves are 4 ft, and the energy is solid (288). That’s a good session.
Sunday the 26th is tricky. The morning is a write-off with onshore wind and a short-period 3 ft swell, but the afternoon has a 4 ft south swell with a very long period of 13 seconds. That’s a proper groundswell with heaps of energy (526), but the wind is light cross-shore, so it’ll be a bit bumpy. That long period will make it fat and straight at the beach, so it’s not the best shape for a paddle – might be more interesting for a kite.
Monday the 27th through Tuesday the 28th morning is a nice little run. Clean, light offshore winds, 2 ft to 3 ft south swell with a period of 11 to 13 seconds. The energy is moderate (320 on Monday morning, 212 on Tuesday morning), and the waves will be clean and holding shape. Not huge, but pleasant.
Then it gets small again. Wednesday the 29th through Thursday the 30th is tiny, with 1 ft to 2 ft swells and very weak energy. It’s surfable but ordinary. Friday the 31st is a dud, with a 30 km/h cross-offshore wind but a 3 ft, 5-second windswell that’s just a mess.
The best of the whole run comes on Sunday the 2nd of August. That morning is outstanding: a 4 ft south swell, 12-second period, and a gentle offshore NE breeze at 15 km/h. The combined energy is a massive 703 – that’s strong, powerful surf. The water is about average for this time of year, and the break is Jaconé, which is exposed to the swell and can get crowded sometimes. This is the one to circle on the calendar. It’s a couple of weeks away, so keep an eye on it, but it’s shaping up to be the best day of the whole forecast.
Monday the 3rd of August morning is also good, with a 4 ft east swell and a moderate offshore wind, but that afternoon gets blown out by a 30 km/h cross-offshore wind. The energy is still there (420), but it’ll be a bit bumpy.
After that, the last few days are small and ordinary, with tiny swells and strong winds – not worth chasing.
So, the standout is Sunday the 2nd of August morning – that’s the one to aim for. The Tuesday and Wednesday mornings are also solid, local options. Otherwise, it’s a bit of a mixed bag with some good, some bad, and some tiny.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
